To the best of our knowledge, this is the first demonstration of SC generation which is directly pumped by an all-fiber noise-like pulse oscillator.
Our work not only validates the superiority of reduced CinSK pulse but also indicates its sensitivity to the initial states, providing practical guidance in the noise suppression domain.
We show that this low-frequency noise is an amplified version of the amplitude noise that is already present on the input laser pulse train.
To the best of our knowledge, this is the first time that the pedestal of a noise-like pulse is compressed to femtosecond region.
The results demonstrate an increase of noise immunity up to one decade compared to the pulse pair method.
The rather wide 3dB spectral bandwidth of the pulse train (25 nm) indicates that they may resemble noise-like pulses.
The observed results would shed some light on the fundamental physics of noise-like pulse as well as its vector features in fiber lasers.
Analytical and simulation results show that the proposed product-based pulse combining is more resistant to noise jamming, as compared to conventional noncoherent pulse integration, under certain conditions.

4 answers
The use of Digital Flexible Ureteroscope with laser in urolithiasis poses several risks and complications. These include ureteroscope damage over time, with acquired imperfections such as shavings, scratches, dents, and discolorations after procedures, potentially increasing maintenance costs. Additionally, the concomitant use of a ureteral access sheath (UAS) during pediatric ureteroscopy can lead to intra- and postoperative complications, including ureteral injuries such as perforation or extravasation, albeit manageable with temporary stenting. Furthermore, image distortion during laser lithotripsy can occur, especially with high power settings and closer distances between the laser fiber tip and the scope, potentially affecting the safety profile and necessitating caution during ureteroscopy procedures.
What are the effects of changing coil alignment on emats?
5 answers
Changing coil alignment in electromagnetic acoustic transducers (EMATs) has significant effects on their performance. Different coil alignments can lead to the generation of Lamb waves or shear horizontal (SH) waves, impacting the wave type produced by the EMATs. Additionally, altering the magnet-to-coil distance can enhance conversion efficiency and reduce the lift-off effect, with a distance of 2 mm being optimal for improved EMAT performance. Moreover, misalignment of coils in inductive powering units can decrease system efficiency, with variations in coil inductance affecting losses differently based on axial distance changes. Furthermore, adjusting coil configurations, such as using a square cross-section, can significantly increase the conversion efficiency of EMATs, showcasing the importance of coil design on EMAT performance.

The spatial resolution of swept-source Optical Coherence Tomography (OCT) can be calculated based on the characteristics of the OCT system. Different systems offer varying resolutions. For instance, a system utilizing an injection seeded terahertz parametric generator (is-TPG) achieved a resolution of 0.2 mm and a depth range of 15 mm. Another system with a swept-source and a Michelson interferometer provided an axial resolution of 15μm and a penetration depth of 12mm. Additionally, an ultrafast swept source at 1050 nm with an 86 nm bandwidth operated at 10 MHz, enabling high-speed imaging suitable for biological tissues. A high-resolution swept source OCT system demonstrated resolutions of one FFT bin for a single reflection, showcasing its high-resolution capability. By incorporating these system-specific parameters, one can calculate the spatial resolution of a swept-source OCT system.

How does the size of cavity air holes affect the resonance wavelength in a certain material?
4 answers
The size of cavity air holes significantly influences the resonance wavelength in various materials. Research demonstrates that modifying the diameter of air holes in photonic crystal structures leads to notable changes in resonance characteristics. For instance, in a two-dimensional photonic crystal slab, a mere 1-nm increase in the lattice constant or air-hole size results in a 4.2-nm increase or 1.56-nm decrease in the resonant wavelength, respectively. Similarly, in photonic crystal fiber gratings, enlarging the air-hole diameter causes a blue-shift in the resonance wavelength, intensifies the resonance peak, and narrows the bandwidth. Conversely, as the collapse degree of cladding air-holes increases, the resonance wavelength red-shifts, transmission enhances, and the bandwidth becomes narrower. These findings highlight the intricate relationship between cavity air hole size and resonance wavelength in different materials.

The relationship between resonance wavelength and cavity air hole size in the given materials is crucial for controlling optical properties. Research by Song et al. demonstrates a linear dependence, where a 1-nm increase in lattice constant or air-hole size leads to a 4.2-nm increase or 1.56-nm decrease in resonant wavelength, respectively. Additionally, Atakaramians and Kuhlmey show that achieving air cavities much smaller than the operating wavelength is feasible under specific conditions of cladding materials, impacting the miniaturization of electromagnetic devices. Hasan and Alam further enhance this understanding by demonstrating deep sub-wavelength broadband evanescent field confinement in low-index materials, improving field intensity, interaction length, and surface sensitivity through rigorous size-dependent air hole modifications.
